IN VENTOR X A TTO RNEV Patented Jan. 26, 1932 UNITED STATES GLEN SAMUEL WALKER, or srnrnenrnnn, onneon ATTACHMENT FOI RIINK BOTTLES Application filed April 3,

My present invention has reference to an attachment for ink wells and my object is the provision of an attachment which will take the place of the usual cork or stopper,

which will remain a permanent fixture upon the well, which is of a construction that will not prevent a pen point or a fountain pen being insertedv in the well for the proper supply of ink, and which will prevent the spilling of the ink should the well be turned over or upset. v

To the attainment of the foregoing the invention consists in the improvement hereinafter described and definitely claimed.

'In the drawings:

Figure 1 is a sectionalview through an ink bottle provided with the improvement, the improvement being also'in section. Figure 2 is a side elevation thereof. Figure 3 is a bottom plan view thereof. The ink containing well or bottle 1 is of the usual construction, being provided with a neck that has an outwardly directed bead. My improvement may be constructed of any desired or preferred material and the upper portion thereof is cylindrical as at 2, and is snugly received in the neck of the bottle or well 1. The bottom edge of the i1npr0vement is rolled outwardly, as at 3, and j is slitted' at determined lengths to provide spaced spring fingers. The rolled portion of the hollow bead 3 is designed to be clamped over the beaded mouth of the neck of the bottle 1 and tightly hold the improvement in the neck of the bottle. From'its cylindrical body 2 the improvement is prefer ably but not necessarily formed with a re duced extension which is square in cross section and which is indicated in the drawings 40 by the numeral 4. The lower and open end of the extension 4 is cut at an angle and this end is normally closed by a valve plate 5 that has a spring end 6 connected to one side of the part 4 of the improvement, the second and lower end of the art 4 being formed with an outstanding lip to'be engaged withthe valve plate 5. r

The spring 6 for the valve plate 5 is of suflicient strength to at all vtimes close the open and lower end of the improvement but ti-shaped notch 11 in the stem of the screw 1931. Serial No. 527,555.

is not of sufiicient strength to resist pressure of a'pen point between the lipped end 7 of the improvement and the valve to swing the valve to open position so that the pen can be replenishedwvith the desired quantity of ink or whereby a fountain pen'may be refilled.

The tubular outer end 2 of the improvement, approximately in a line with the side ofthe squared portion 4 thereof provided with the lip 7, has a passage 8 therethrough, and this passage is closed by a milled headed screw a plug 9 that is suspended from the spring bead 3 through the medium of a flexible element such as a chain 10. If de- 'sired,the shank of the screw may be notched. The screw, when withdrawn permitsof the passage of air'into the ink well or a desired quantity of air may be admitted through the whenthe head thereof is brought away from the flatouter face of the improvement provided between the head 3 and the passage8. The improvement in no ways retards the use -of ink contained in the well when pens are to have their ink supply replenished. The valve plate 5, through the medium of the spring end 6 thereof, however, at all times covers the lower open end of the improvement so that should the bottle or well 1 become tilted or upset no ink can flow there from, the closed valve 5 retarding and preventing such passage of ink. v

' The spring-.6 of the valve body may beintegrally form ed with the said valve and'with the part4 of the device or may comprise a separate member. The part 4 at the portion tiereof provided with the spring 6 is rounded or bulged outwardly so that the same will offer no obstruction to the pen when pressed against the valve. The spring, of course, must be of a construction to render the valve leak proof and the outer portion of the valve, which contacts with the lip 7 is preferabl rounded upon itself, as disclosed by the draw-' ings.

It is thought the foregoing description will fully set'forth theconstruction and advantages of the improvement to those skilled in the art to which the invention relates so that further detailed description will not be required. Obviously I do not wish to be restricted to the precise details herein set forth and, therefore, hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim.

IIaving described the invention, I claim:

, 1. An attachment for ink containing bet- I t-les, comprising a tubular member having a m beaded mouth which is slit to afi'ord the same with spring fingers arranged over and in frictional contact with the beaded end of the neck of the bottle, said member having a reduced extension which enters the bottle and terminates above the level of the ink therein, and which extension has its lower outer end inclined, a valve plate for closing the said end and a spring for the valve plate normally holding the same closed.

2. An attachment for ink containing bottles, comprising a tubular member having a beaded month which is slit to afford the same with spring fingers arranged over and in frictional contact with the beaded end of the g5 neck of the bottle, said member having a reduced extension which enters the bottle and terminates above the level of the ink therein, and which extension has its lower outer end inclined, a valve plate for closing the inner and open end of the member, said valve plate having an arched spring at one end thereof secured to the member and normally swings the valve plate to closed position and a lip on the member with which the valve plate 36 contacts. 7

3. An attachment for ink containing bottles, comprising a tubular member having a beaded mouth which is slit to afford the same with spring fingers arranged over and in fric 40 tional contact with the beaded end of the neck of the bottle, said member having a reduced extension which enters the bottle and terminates above the level of the ink therein, and which extension has its lower outer end in- 5 clined, a valve plate for closing the inner and open end of the member, said valve plate having an arched spring at one end thereof secured to the member and normally swings the valve plate to closed position and a lip on the member with which the valve plate conacts, the tubular portion of the member having a passage therein, a screw having a knurled end threaded through the top of the member in a line with the passage, and a flexible support between the split beaded mouth of the member and the screw.

In testimony whereof I atlix my signature.

GLEN SAMUEL WALKER.
